AUTOMATIC CAR-LOADlNG APPARATUS- Specification of Letters Patent.

:atented July 3, 1906.

Application filed October 10, 190 Serial No. 227,837.

To all whom it may concern:

Be it known that I, WILLIAM J SELLEOK, a citizen of the United States, residing at Riverside, county of Fairfield, State of Con necticut, have invented-a certain new and use ful Improvement in Automatic Car-Loading Apparatus; and I declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it pertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of this specification.

My invention relates in general to loading apparatus, and more particularly to apparatus for automatically loading material upon moving. cars.

In loading material, such as coal, upon cars it has heretofore been necessary to stop each car in proper position relatively to the loading apparatus and allow it to remain stationary While being filled. Such an operation requires considerable time, as it is necessary that each car should belocated in an exact position to receive the material and remain in such position while receiving the material.

The object of my invention is to provide a loading apparatus by means of which moving cars may be successively filled with material automatically as they pass a given point without requiring them to stop.

A further object of my invention is to provide a loading apparatus for automatically delivering material to moving cars which will be automatically rendered inoperative when the supply of material is exhausted.

A still further object of my invention is to provide an apparatus for automatically loading material upon moving cars which will be comparatively simple in construction, strong and durable in use, and eflicient in operations My invention, generally described, consists in a chute, a measuring-receptacle for receiving the material from the chute, a motor for oscillating the receptacle to deliver the material therefrom into-a passing car, mechanism actuated by a trip .on a car for operatively connecting the motor to the measuring-receptacle to oscillate the latter, and means actuated by the material in the chute for connecting said mechanism with the motor and for disconnecting said mechanism, and therebyinterrupting the operation plan view; Fig. 3, a plan view from beneath the chute; Fig. 4, a sectional view on line 4 4, Fig. 3; Fig. 5, a sectional view on line 5 5, Fig. 3; Fig. 6, a sectional view on line 6 6, Fig. 5; Fig. 7, a sectional view of the chute and measuring-receptacle on line 7 7, Fig. 2; Fig. 8, a sectional view on line 8 8, Fig. 7;

Fig. 9, a sectional view on line 9 9, Fig. 7;

Fig. 10, a detail view of the car-tripping mechanism; Fig. 11, an enlarged sectional view of the shaft interposed between the cartripping mechanism and the motor-clutch; Fig. 12, a detail sectional view on line 12 12, Fig. 3; and Fig. 13, a sectional view on line 13 13, Fig. 5.

The same reference characters are used to designate-the same parts in the several figures of the drawings.

Referring to Fig. 1, reference-letter A designates a (tie upon which is supported the rails a of a track.

A designates a car of the self-dumping type, the trucks a of which engage the rails a of the track.

a indicates a bracket rigidly secured to and projecting laterally from the car A, de signed to engage and put in operation mechanism for filling the car with a predetermined material.

Reference characters B, B and B indicate vertical posts which support in an elevated position above the railroad-tracks the loading apparatus. B and B designate horizontalbeams, such as channehbars, which are supported by the posts B B at a hei ht slightly above the tops of the cars. Suita le struts are provided for rigidly securing the horizontal beams B and B to the posts such, for instance, as the channel-bars b b, which extend downwardly from the posts B and B to the ends of the beams B and B at the rear of the track, and channel-beams I) and 5 which extend from the posts B B to the horizontal beams B and B at,,points above the track. Other suitable braces,

such as 6 (see Fig. 1,) may be provided where necessary to impart to the supporting structure the requisite strength.

0 designates a hopper into which material is delivered from any ordinary supplysuch, for instance, as coal-pockets. C designates a chute leading in an inclined direction from the hopper C. The chute 0 extends between and is supported by the posts B and B in any suitable manner. The lower end of the chute terminates adjacent to the outer surface of a drum D. An opening is formed through the drum D of a size corresponding to the crosssection of the chute. Located within the drum is a measuring-receptacle d, the opening into which registers with the opening through the drum, as clearly shown in Fig. 7. The top of the chute adjacent the drum is closed by an upwardly-yielding cover O hinged at its upper edge to the top wall of the chute and provided with side wings C extending within and lying adjacent to the side walls of the chute. In order that there may be no opening between the bottom of the chute and the surface of the drum, an extensible strip C preferably angular in cross-section, is secured beneath the chute by means of slots and bolts and is proj ected against the surface of the drum by one B the ends of the journals (1 and (Z projecting beyond the bearings therefor and provided with gear-wheels E and E which mesh with larger gear-wheels F and F fixed upon the ends of a shaft F, the latter being suitably journaled in bearings f, secured to the beams B and B The gear-wheels F and F are provided with wristpins, to which are pivotally connected links f and f the opposite ends of such links being'pivotally connected to crank-arms G and G respectively, projecting from a crank-shaft G, the latter being journaled in bearings g, fixed upon the horizontal beams B and B The power-shaft H is journaled in bearings h, fixed upon the horizontal beams B and B and is provided with a gear-wheel H which meshes with a larger gear-wheel G fixed upon the crank-shaft G. Any suitable motive power may be employed for rotating the power-shaft H such, for instance, as a vertical engine w, the shaft W of which is rotatively connected to the power-shaft H by means of meshed gear-wheels W and H, mounted, respectively, upon the engine-shaft and power-shaft.

In order that the engine or other motor may run constantly and only be effective to upon the casting 0.

rotate the drum D when a car is in position to receive the coal or the material therefrom, the following clutching mechanism is em ployed: A shaft M is journaled at one end in a bearing 17/, depending from a beam B, the opposite ends of the latter being rigidly supported by the transverse beams B and B.

The other end of the shaft M is journaled in a bearing a, mounted upon a supporting-block N, the latter being rigidly secured to the beam B. A crank-arm K is fixed to the shaft M and is connected, by means of a rod 7c, with a short lever K, the latter being pivotally mounted at its lower end in a bracket 5 depending from an angular beam B The upper end of the lever K is provided with an antifriction-roller, which is adapted to ride upon a cam-track g rigidly secured to the spokes of the gear-wheel G as clearly shown in Figs. 5 and 6.

A second crank-arm L is fixed to the shaft M and extends at an approximately right angle to the crank-arm K, 1 The outer end of the crank-arm L is pivotally connected to a vertical rod L, which projects upwardly through the hole in a boss Z on the end of the lever L and also through the hole in a boss on one arm of a bell-crank lever L as will be understood by reference to Fig. 5. A weight Z depends from the end of the crankarm L, which serves to oscillate the shaft M, so as to throw the upper end of the lever K toward the gear-wheel G The lever L is pivotally supported upon a lug depending from a casting O, the latter being supported by the block N. The bellcrank lever L is also pivotally supported A vertically-reciprocating rod. 0 extends through alined holes in brackets 0 and 0 which project from the casting O. The lower end of the rod 0 is provided with a recess into which extends the end of the lever L A spacing-tube Z surrounds the rod L and is interposed between the alined bosses on the lever L and L Splined upon the power-shaft H is a clutch H having laterally-projecting inclined teeth 7L2, adapted to engage cooperating teeth h, fixed to the gear-wheel H, the latter being loosely j ournaled upon the shalt H. A cam 0 projects laterally from a radial flange around the periphery of the clutch member H and is adapted to be engaged by the upper end of the rod 0, as shown in Fig. 5, to dis engage the teeth on the clutch member from the teeth on the gear-wheel H. A circular groove is formed in the clutch member H into which extend the inwardly-projecting ends of a yoke Z the latter being rigidly secured to and forming part of the bell-crank lever L A third crank-arm m projects upwardly from and is rigidly secured to the shaft M and is provided with a hole through its upper end. A rod M extends through a'hole in the arm ILO ally-projecting semicircular'lug, asclearly shown in Fig. 11. Depending from the collar T is a hanger T the lower end of which is pivotally connected to a horizontal shoe U.

' A. second hanger T for supporting the shoe U depends from a rod i suitably supported, as, for instance, in a bearing t secured to the upper surface of the beam' B The other end of the rod i may be conveniently supported in a strut 6 which extends from the end of the beam B across the beam B to which it is rigidly secured. The shoe U is preferably provided with an extensible portion a, by means of which the length of the shoe may be adjusted to insure the operation of'the loading apparatus at the instant the car is inposition to receive the material from the measuring-receptacle d.

Surrounding and splined upon the shaft P is a sleeve P one end of which has fixed thereon a collar T, having a laterally-proj ecting semicircular lug adapted to cooperate with the lug on the collar T to non-rotatively lock the hangerT to the shaft P. A disk surrounds and is secured to the end of the sleeve P opposite the collar T, while a similar disk p loosely surrounds the shaft P adjacent to crank-arm P. A collar r loosely surrounds the shaftP, between which and the end of the sleeve P is interposed a coilspring R. Tie-rods 19 (see Fig. 3) connect the disks 0 and p r The bell-crank lever S is j ournaled upon a rod 8, the latter being shown in Fig. 1 as journaled upon the strut b and extending through a bearing 8 upon the beam 1)", and the upper end of one of the arms of the bell-crank lever is bifurcated, so as to extend on opposite sides of the shaft P at a point intermediate of the disk 7) and collar 1". The other arm of the bell-crank lever S is connected by a rod S to a crank-arm S which is rigidly secured to a shaft S The shaft S extends through the chute C, near the upper end thereof. The shaft S is journaled in brackets 8 secured to the inner surface of the top of the chute, as shown in Figs. 7 and 9, and is also journaled in a bearing 8", mounted upon a beam 8, which projects laterallyfrom a beam b of the supporting structure. Depending from and rigidly secured to the shaft S within the chute is a gate (1 the latter adapted to be swung upwardly by the material in the chute, and thereby rock the shaft S Rigidly secured to the end D of the drum is a disk D around which extends a brakeband (Z One end of the brake band is rigidly secured to a pin (1, (see Fig. 4,) and the other end is pivotally connected to a lug projecting from a collar f, the latter being loosely supported upon the shaft F. Extending from and rigidly secured to the collar f is a lever F The free end. of the lever F projects above the shaft G and is adapted to be engaged by either one of two cams g and 9 which project radially from and are rigidly secured to the shaft Gr. The cam g is slightly longer than the cam g, as will be seen by reference to Fig. 4.

A hood C is preferably located partially around the drum D and is supported upon curved beams c and c, which project upwardly from the beams B and B and are secured at their upper ends to the inclined beams b and 6 The upper end of the hood C is secured to a transverse angle-bar C mounted at its opposite ends upon the supports 0 and 0 In order to give suflicient rigidity to the supports a and 0 a transverse angle-bar 0. extends across the same, the latter being rigidly secured at its ends to vertical bars a and c Whichproject upwardlyfrom the inclined strut b and b The lower end of the hood C is extended downwardly below the beam 13, as shown at V, to form a deflector for directing the material into the A similar guide or deflector V extends beneath the drum and is supported by suitable strips 4) and 12 depending from the hori zontal beams B and B In order to prevent the rotation of the shaft. G after it has rotated the desired amount to bring the receptacle (1 into alinement with the chute, lugs n and n project from the ends of the crank-arm G and G and are adapted to be received in recesses formed in vertical leaf-springs n and 17/, respectively, the latter being mounted in vertical channelbars N and N which are rigidly secured to bars N and N projecting from and supported by the horizontal beams B and B.

The operation of my invention is as follows: The coal or other'material deposited in the hopper C passes into the chute C, thence into the measuring-receptacle cl in the drum D. The material within the chute C elevates the gate C therein, so that the shaft S is oscillated, thereby swinging upwardly the crank-arm S which, through the interposed rod S, oscillates the bell-crank lever S in a direction to force the collar 1" on shaft P toward the left in Figs. 1 and 11. The movement of the collar 7* through the interposed spring R slides the sleeve P upon the shaft P, so that the semicircular lugs on the collar T and T are brought into engagement, thereby locking the hanger T 4 to the shaft P. The passage of a car beneath the shoe U causes the bracket a on the car to engage the shoe and swing the same in the direction in 1 turned to its first position, in which the open 6 5 which the car is moving. The shaft P is consequently rocked and the crank-arm P thereon partially rotated, so that'a tension is applied to the rod M, which, through its engagement with the arm m, oscillates the shaft M. 'The oscillation of the shaft M swings upwardly the crank-arm L thereon, thereby rocking the levers L and L through the medium of the rod L and interposed tube Z. The movement of the lever L withdraws the rod 0 from the path of the cam 0, while the oscillation of the bell-crank lever L forces the clutch members H toward the gear- Wheel H through the engagement of the yoke Z with the groove in the clutch member. The teeth k are consequently forced into engagement with h and the gear-wheel H rigidly connected to the shaft H Rotary motion is consequently imparted to the shaft H from the motor a, and such rotary motion is transmitted to the shaft G through the meshed gear wheels H and G The respective directions of rotation of the gearwheels is indicated by arrows in Fig. 1, by which it will be seen that the rotation of the shaft G swings downwardly the crank-arms 'G and G thereby partially rotating the gear-wheels F and F which through the gear-wheels E and E oscillate the drum through approximately two hundred and ten degrees, so that the opening of the measuring-receptacle d occupies a position above thecar and the material therefrom is deposited into the car, passing between the deflectors V and V.

The oscillation of the shaftMswings the lever K away from the cam-guide 9 so that the rotation of the gear-wheel G brings the cam-guide beneath the roller 7c and retains the lever K, and consequently the shaft M through the connecting-rod 1c, in the positions to which they have been moved by the shoe Unamely, in position to clutch the gear-wheel H to the shaft H and continue the operation of the apparatus sufficiently to impart two revolutions to the shaft H, which, as the periphery of the gear-wheel H is onehalf that of the periphery of gear wheel G effects one complete rotation of the shaft G. The size of the gear-wheels F and F relatively to the meshed gear-wheels E E is such that the rotation of the shaft G through one hundred and eighty degrees oscillates the gear-wheels F and F sufficiently to rotate the drum the desired amount to bring the opening of the measuring-receptacle from its position in alinement with the chute to a position above the car. The continued rotation of the shaft G through one hundred and eighty degrees oscillates the gear-wheels F and F in a reversed direction, and such reversed direction is communicated to the gearwheels E and E so that the drum is reing of the measuring-receptacle alines with the chute.

Immediately upon the shaft G completing a revolution the lever K is disengaged from the cam-guide g and swung toward the gearwheels by the weight Z through the interposed crank-arms L and K, shaft M, and connecting-rod 7c. The oscillation of the shaft M, due to the weight Z, draws downwardly the rod L, which oscillates the lever L and forces upwardly the rod 0, so that the upper end thereof is projected in the path of the cam 0, and the latter, through engagement with the upper end of the rod 0, forces the clutch member H away from the gear-wheel H, thereby disengaging the teeth h from the teeth h. The motor is therefore disconnected from the shaft H, and the drum remains in position for the measuring-receptacle to receive material from the chute until the bracket on another car engages the shoe U and again puts the apparatus into operation,

In order to insure the drum stopping in the position in which the mouth of the receptacle d alines with the chute, the cam g is provided on the shaft G, which engages the outer end of the lever F and oscillates the latter, so that the brake-band (Z tightly engages the brakedisk D and immediately stops the rotation of the drum. The cam g on the shaft G is shorter than the cam 9 as it engages the lever F when the drum has been rotated to dump the material from the receptacle. It is not necessary that the brake-band should bind upon the brake-disk with the same force when the drum is in position to dump the material as it is when the drum is rotated rotated into position for the receptacle to receive material from the chute the clutch has been disengaged, so that if it were not for the operation of the brake-band the drum would from its own momentum rotate farther than necessary, and consequently the mouth of the receptacle would not accurately aline with the chute.

In order to insure the complete stoppage of all of the parts of the apparatus, except the engine and gear-wheel H, the lugs n and 'n, on the ends of the crank-arms G and G are provided, which engage within the grooves in the spring-plates n and 'n, immediately upon the operation of the brake-band by the cam the chute, the gate ply of material is exhausted.

parts.

When there is no longer any material in falls by gravity to the position shown in Fig. 7,, thereby oscillating the shaft S and swinging .downward the crank-arm S thereon, so that the spring R is permitted to expand thereby through the interposed bifurcated end of the bell-crank lever S, the disk 19 and the tie-rods 19 moving the sleeve P toward the right and disengaging the lugs on thecollars'T and T The hanger T may then swing idly upon the shaft P until the shoe U is engaged by the bracket a on the passing car. Immediately upon coal being deposited in the chute the gate 0 is swung upwardly and the hanger T clutches to the shaft P through the interposed mechanism. I

In order to avoid damage to the upper wall of the chute by means of lumps of coal or other material being forced against the lower edge thereof by the lower wall of the receptacle d, the swinging cover 0 is provided, which merely swings upwardly to permit the material to pass with the drum out of the chute. The depending wings C prevent material falling over the sides of the chute when the cover C is swung upwardly. A close contact is always maintained between the outer surface of the drum and the lower edge of the bottom of the chute owing to the springpressed plate C It is necessary that the shoe U should be so placed with respect to the drum that after the car has actuated the shoe the drum will be oscillated and the material delivered therefrom at the'exact instant the car is in position to receive the same. The adjustable end it of the shoe permits such a timing of the operation of the mechanism as to insure the rotation of the drum and the dumping'of the material from the receptacle therein at the exact instant the car is in position to receive the same.

From the foregoing description it will be observed that I have invented an improved apparatus for automatically loading material upon a passing car, the operation of which is automatically discontinued when the sup- It is obvious that my invention is capable of use whereever coal or other material is to be handled,

both in connection with cable-cars employed for transferring coal from one point to another and in the loading of freight-cars as well.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit of my invention.

what I claim as new, and desire to secureby Letters Patent, is
